Biventricular pacing for the treatment of congestive heart failure is now one of the forefront therapies for symptomatic heart failure patients who are receiving maximal medical therapy. Recent advances in lead technology and delivery systems have improved the success rates of left ventricular (LV) lead implantation. A major difficulty in LV lead implantation, however, occurs in patients with coronary vein stenoses, insufficient coronary vein caliber, or significant variations in coronary venous anatomy, in terms of left ventricular lead implantation. We sought to examine whether cardiac vein angioplasty and/or stenting would allow for the proper placement of the LV lead in these patients.
双心室起搏治疗充血性心力衰竭，目前是接受最大程度药物治疗的有症状心力衰竭患者的前沿治疗方法之一。导线技术和输送系统的最新进展提高了左心室（LV）导线植入的成功率。然而，就左心室导线植入而言，LV导线植入的一个主要困难发生在患有冠状静脉狭窄、冠状静脉管径不足或冠状静脉解剖结构显著变异的患者中。我们试图研究心脏静脉血管成形术和/或支架置入术是否能使LV导线在这些患者中正确放置。
